🔒 Files never leave your device — everything runs in your browser.
GIF refuses to die for one good reason: it plays everywhere, instantly, with no play button, no sound permissions, no player chrome — in chat apps, forums, READMEs, issue trackers, and documentation. Turning an MP4 moment into a GIF is still the most reliable way to make a clip loop in places built for images.
ConvertUno decodes your MP4 with hardware acceleration and builds the GIF frame by frame on your device — 12 frames per second at up to 480 pixels wide, the sweet spot where loops stay smooth and files stay postable. A word of honest advice: GIF is an ancient format that grows fast — it shines for moments under about fifteen seconds. Trim first, loop forever.

Frequently asked questions
Why is my GIF bigger than the MP4 it came from?
Because GIF is a 1987 image format, not a video codec — it stores every frame as a compressed image with a 256-color palette, with none of modern video's motion tricks. That is the price of playing literally everywhere. Keep clips short and the trade stays worth it.
What settings does the GIF use?
12 frames per second at up to 480 pixels wide (aspect preserved, never upscaled) — the classic sweet spot for smooth, postable loops. The audio track is dropped, as GIFs have no sound.
How long a clip should I convert?
Under about 15 seconds is the GIF happy zone; a few seconds is ideal. Longer clips convert fine but produce heavy files that some platforms refuse — for anything long, a compressed MP4 is usually the better share.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
